* Add an OpReinterpret operation to TableGen's NeonEmitter.Bob Wilson2010-12-072-40/+73
| | | | | | | | An OpReinterpret entry is handled by translating it to OpCast intrinsics for all combinations of source and destination types with the same total size. This will be used to generate all the vreinterpret intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121087 91177308-0d34-0410-b5e6-96231b3b80d8

* Support using macros for Neon intrinsics implemented without builtins.Bob Wilson2010-12-031-49/+58
| | | | | | | | Intrinsics implemented with Clang builtins could already be implemented as either inline functions or macros, but intrinsics implemented directly (without builtins) could only be inline functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120763 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify code in Neon intrinsics. No functional changes intended.Bob Wilson2010-12-021-43/+37
| | | | | | | For most intrinsics, there is no need to allocate a temporary to hold the result value; just return it directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120695 91177308-0d34-0410-b5e6-96231b3b80d8
* Assign arguments of Neon intrinsic macros to local temporaries.Bob Wilson2010-12-021-4/+31
| | | | | | | | Since we're casting them for the calls to the builtins, we need this to make sure their types get checked in the same way they would if the intrinsics were implemented as inline functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120693 91177308-0d34-0410-b5e6-96231b3b80d8

* Change the 'x' type modifier for Neon intrinsics to force a signed integer.Bob Wilson2010-11-181-0/+5
| | | | | | | | This makes it symmetric with the 'u' modifier that forces an unsigned type. This is needed for unsigned vector shifts, where the shift amount still needs to be signed.

* Remove ARM isel hacks that fold large immediates into a pair of add, sub, and,Evan Cheng2010-11-173-0/+3
| | | | | | | | | | | | | | | | | | | | | | and xor. The 32-bit move immediates can be hoisted out of loops by machine LICM but the isel hacks were preventing them. Instead, let peephole optimization pass recognize registers that are defined by immediates and the ARM target hook will fold the immediates in. Other changes include 1) do not fold and / xor into cmp to isel TST / TEQ instructions if there are multiple uses. This happens when the 'and' is live out, machine sink would have sinked the computation and that ends up pessimizing code. The peephole pass would recognize situations where the 'and' can be toggled to define CPSR and eliminate the comparison anyway. 2) Move peephole pass to after machine LICM, sink, and CSE to avoid blocking important optimizations. rdar://8663787, rdar://8241368 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119548 91177308-0d34-0410-b5e6-96231b3b80d8

* This is the first step in adding sane error handling support to LLVMSystem.Michael J. Spencer2010-11-164-1192/+1
| | | | | | | | | | | | | | | | | The system API's will be shifted over to returning an error_code, and returning other return values as out parameters to the function. Code that needs to check error conditions will use the errc enum values which are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are compatable with the error codes in WinError.h due to some magic in system_error. An example would be: if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool. handle_error(ec); } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119360 91177308-0d34-0410-b5e6-96231b3b80d8
